BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Thigmotropism is the directional growth movement of a plant in response to touch or contact stimuli. It is found in twining plants or tendrils which grow around a surface such as a wall, pot, or trellis. The word Thigmotropism is derived from “Thigmo” means “Touch or Contact” and “Tropism” which means “Directional”.

Detailed explanation-2: -Thigmotropism works much like the other tropisms. The plant grows straight until it comes in contact with the pole. Then, the side of the stem that is in contact with the pole grows slower than the opposite side of the stem. This causes the stem to bend around the pole.

Detailed explanation-3: -This is a type of rapid plant movement called thigmonasty or seismonasty or haptonasty and comes as a direct reaction to physical contact.

Detailed explanation-4: -Thigmotropism is a plant’s response to touch. Stems of many vines show positive thigmotropism when they encounter something and wrap themselves around it. Hydrotropism is plants’ growth in response to water. Plants are able to respond to light, gravity, and touch because they produce hormones.
